Nucleotide Frequencies in Human Genome and Fibonacci Numbers [PDF]

open access: yesBulletin of Mathematical Biology, 70, 643-653,2008, 2006
This work presents a mathematical model that establishes an interesting connection between nucleotide frequencies in human single-stranded DNA and the famous Fibonacci's numbers. The model relies on two assumptions. First, Chargaff's second parity rule should be valid, and, second, the nucleotide frequencies should approach limit values when the number

A flexible model-based framework for robust estimation of mutational signatures [PDF]

open access: yesarXiv, 2022
Somatic mutations in cancer can be viewed as a mixture distribution of several mutational signatures, which can be inferred using non-negative matrix factorization (NMF). Mutational signatures have previously been parametrized using either simple mono-nucleotide interaction models or general tri-nucleotide interaction models. We describe a flexible and

The evolution of nucleotides

open access: yesAdvances in Space Research, 1986
There has been much speculation about the types of molecules that were present in the first living forms. Recent discoveries show that RNA is a more versatile molecule than was previously believed, but whether it was ever able, for example, to synthesize its own monomers from available precursors is not yet known.

Distantly related sequences in the alpha‐ and beta‐subunits of ATP synthase, myosin, kinases and other ATP‐requiring enzymes and a common nucleotide binding fold.

open access: yesEMBO Journal, 1982
The alpha‐ and beta‐subunits of membrane‐bound ATP synthase complex bind ATP and ADP: beta contributes to catalytic sites, and alpha may be involved in regulation of ATP synthase activity.

Genome-Wide Analysis in Vivo of Translation with Nucleotide Resolution Using Ribosome Profiling

open access: yesScience, 2009
Techniques for systematically monitoring protein translation have lagged far behind methods for measuring messenger RNA (mRNA) levels. Here, we present a ribosome-profiling strategy that is based on the deep sequencing of ribosome-protected mRNA ...

Exploring the nucleotide molecular mechanism of compound kushen injection for lung adenocarcinoma based on network pharmacology and molecular docking

open access: yesFrontiers in Oncology, 2022
Compound kushen injection is an effective traditional Chinese medicine for the treatment of lung cancer. However, its influence on the survival and prognosis of patients with lung adenocarcinoma patients was less studied; especially its pharmacological ...

Towards a taxonomic coherence between average nucleotide identity and 16S rRNA gene sequence similarity for species demarcation of prokaryotes.

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2014
Among available genome relatedness indices, average nucleotide identity (ANI) is one of the most robust measurements of genomic relatedness between strains, and has great potential in the taxonomy of bacteria and archaea as a substitute for the labour ...

MatInd and MatInspector: new fast and versatile tools for detection of consensus matches in nucleotide sequence data.

open access: yesNucleic Acids Research, 1995
The identification of potential regulatory motifs in new sequence data is increasingly important for experimental design. Those motifs are commonly located by matches to IUPAC strings derived from consensus sequences.
